This portrait of Dorothy Thornhill is by her husband Douglas Dundas. Dorothy attended the National Art School at East Sydney Technical College from 1929–32 and was a student of her future husband. Dressed in a chartreuse green jacket with leg-o-mutton sleeves, Dorothy exudes a casual elegance.

She was an accomplished artist and also taught at the National Art School for almost 40 years. The pair married in 1941 and shared a studio in Edgecliff.
